Polymer Lithium Ion Battery - 40mAh (JST-SH)

This extremely tiny and lightweight battery leverages the advanced Polymer Lithium Ion chemistry, boasting the highest energy density currently available. It delivers a nominal 3.7V at 40mAh, packing substantial power into a cell that's just about 1.27cm square.

Equipped with a standard 2-pin JST-SH connector with 2mm pin spacing, this battery requires specialized charging. It includes built-in protection against over voltage, over current, and minimum voltage. For wearable projects, caution is advised when using conductive thread to avoid shorts that could create sparks and heat. Beginners are recommended to use coin cell batteries instead.
